Can you adjust the entry delay timer on this alarm system?

Absolutely! There are 2 ways you can do this: #1 FROM THE DISPLAY: select Menu - Timer - Disarm Timer #2 FROM SMART LIFE APP: Select "Settings", then select "Entry Delay". Here you can select from 0 to 299 seconds! We recommend using a short timer between 1-3 seconds so the alarm system goes off quickly after an intruder breaks in. Having a short timer would mean that you will not have much time to enter your code when you enter the house. Therefore, we suggest that you use the app on your phone or the wireless remote controller to disarm your system as it by passes the need to enter your code.
